Cold vs Allergy: A Family Friendly Cheat Sheet for Sniffly Season

You know the drill. A runny nose turns into a late night Google spiral. But instead of scrolling through conflicting advice, we’ve pulled together what you need to know with help from Codral and Zyrtec. Colds and allergies often look alike, but they behave differently – and choosing the right treatment depends on spotting the difference. Let’s break it all down: what symptoms to look for, how long they usually last, and which products can help you (and your family) bounce back faster.

Cold symptoms tend to:

• Develop gradually over a few days

• Last around 3–10 days

• May come with fatigue, a sore throat or mild fever

• Can include sneezing, and coughing

• May make your whole body feel a bit run down

Allergy symptoms usually:

• Start suddenly, often after exposure to a trigger (like pollen or dust)

• Can include hives

• Stick around for weeks – or longer if untreated

• Can include sneezing, a runny nose and itchy eyes

• Don’t come with fever

• Often return at the same time each year (hello, hay fever season)

We’ve all been there. Sniffles on the train, sneezes in the office and that creeping feeling that you're likely next in line for this winter's cold. When it hits you know it'll pass, of course, but what should you look out for? Colds can come with a mix of body-wide symptoms like fatigue, headaches, and fever. If you have a sore throat, are feeling fatigued and have a stuffy and runny nose, you’re likely dealing with a cold^[1].

Codral Cold & Flu Day & Night Tablets – formulated for the temporary relief of cold and flu symptoms, including runny nose, congestion, headache, body aches, and fever. The day tablets help relieve your symptoms to power through your day, while the night tablets include an antihistamine to relieve symptoms and help you rest. Codral is Australia’s #1 cold and flu brand^[2] for a reason – trusted by Aussies for fast, effective relief.

Most colds follow a predictable pattern – starting slow, peaking around day two or three, and tapering off by day seven to ten. It’s not fun, but at least there is an end in sight. Common symptoms like sore throat, congestion and fatigue tend to show up early and ease off after a few days, while coughs (both dry and chesty) often stick around the longest – sometimes even after you’re feeling better.

On average, cold symptoms last about eight days, with fatigue and cough often lingering beyond the worst of the illness^[3]. If your symptoms come on gradually, have changed over time, and include full-body tiredness or a low grade fever, it’s more likely to be a cold than an allergy.

If you’ve got itchy eyes, a runny nose, and no other major symptoms – allergies might be to blame. Hay fever (allergic rhinitis) can strike year-round or be triggered seasonally, and symptoms often come on suddenly, when exposed to triggers like pollen, dust, or pet dander.

Zyrtec Rapid Acting Mini Tablets – provide fast-acting, 24-hour relief from hay fever and allergy symptoms. The small, easy-to-swallow tablets work quickly to help relieve sneezing, runny nose, itchy eyes, and more – so you can get on with your day.

Unlike colds, which usually clear up in under 10 days, allergy symptoms can hang around for weeks – or even months – depending on your triggers. In Australia, different regions have different pollen seasons, and certain grasses, weeds, and plants release pollen over extended periods^[4].

If your symptoms pop up at the same time each year, or linger long after everyone else’s cold has cleared, there’s a good chance allergies are to blame. Keeping track of when and where symptoms strike – and whether they’re linked to time outdoors, dust, or pets – can help pinpoint what’s really going on.

Runny noses, itchy eyes, crankiness – colds and allergies love causing chaos in kids’ routines. Colds typically pass within a week, but in the meantime they can leave kids feeling tired, congested and cranky – often needing time off school and plenty of rest and fluids.

Allergies, on the other hand, can stick around much longer. And unlike a cold, they don’t come with a fever. Instead, you might notice sneezing, a runny nose, itchy eyes that don't seem to go away. Symptoms often appear at the same time each year, or flare up around things like dust, pets or changes in the weather. Keeping track of when and where symptoms show up can help you spot potential triggers – and whether it’s time to explore allergy support^[4].

Whether you’re dealing with a cold or allergies, getting the right treatment depends on identifying your symptoms correctly.
